Multiband Electronic Structure of Magnetic Quantum Dots: Numerical Studies (1707.01565v1)

Abstract: Semiconductor quantum dots (QDs) doped with magnetic impurities have been a focus of continuous research for a couple of decades. A significant effort has been devoted to studies of magnetic polarons (MP) in these nanostructures. These collective states arise through exchange interaction between a carrier confined in a QD and localized spins of the magnetic impurities (typically: Mn). We discuss our theoretical description of various MP properties in self-assembled QDs. We present a self-consistent, temperature-dependent approach to MPs formed by a valence band hole. We use the Luttinger-Kohn k.p Hamiltonian to account for the important effects of spin-orbit interaction.
